low fps

Cvar limit is 2, nothing higher will do anything

It's not true. You can check it yourself ingame, by changing r_lodbias to different values, while standing in front of a player.
With a high lodbias you will get the simplified player model you normally have from a distance, even in close range.

ET is CPU based, rather than using a graphics card. That's why I get high FPS on Skyrim but not on ET

He said cod takes more resources than et. He probably just thought 'et is old, so it uses less resources', so it was (probably) just a guess, he (probably) didn't do any kind of benchmark nor checked cpu or gpu usage in any way. My comment was just about that, I didn't want to go into details.

p.s.
your low graphic config has some cvars which are limited in many servers (etpro especially), for example r_subdivisions and r_lodcurveerror.
r_simpleMipMaps 0 is slower than 1
